SPECIFICATION forming part of Letters latent No. 687,179, dated November 19, 1901. V Application nea nach 6,1901. serai No. 50,044. (Nomaden To all whom it may concern:

Be it known that we, JAMES DAMEY and WILLIAM H. CORK, citizens of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Heater, of which the following is a specification.

Our invention relates particularly to heaters having connected therewith a hot-watersupply circuit and a steam or hot-water heating circuit.

Our primary object is to provide a heater of this nature of simple construction, of great heating capacity, and capable of economical operation at all seasons of the year.

O ur invention is illustrated in its preferred form in the accompanying drawings, in which- Figure 1 is a vertical sectional view of a heater embodying our improvements; Fig. 2, a transverse section taken as indicated at line 2 of Fig. 1; Fig. 3, an enlarged broken vertical section at the upper portion of the heater; Fig. fi, a similar section illustrating a modification of the connections of the hotwater chambers with the circuits, and Fig. 5 a broken detail View of a removable inner fire-pot employed.

A represents a base for the heater; B, an annular water-chamber of well-known general form supported thereon; C, an inclosing drum supported on said base and projecting above the top of said chamber; D, an inner annular water-chamber supported by a flange a, which rests upon the upper end of the chamber B; E, an inner drum dividing the space between the chambers B and D into annular spaces b and b; F, a fuel-magazine separated from the chamber D by a space c; G, a removable inner fire-pot depending from the lower end of the chamber D to near the main grate G' and comprising separable sections c' c2; H, an upward extension for the magazine F, the same being provided with a lid H', whereat fuel may be introduced; I, a shallow Water chamber or steam dome through which the extension H projects and which affords a top for the heater; J, outgoing pipes; K, pipe connections between the chambers D and I; L, pipe connections between the chambers B and I; M, return-pipes having branch pipes M' and M2 connected, respectively, with the outer and inner chambers; M3, conduits for the pipes M2; N, a halfannular plate, which closes the upper end of the annular outer space d at one side of the furnace; N', vertical partitions extending downward from the ends of the plate N and dividing the space d vertically; P, a smokestack provided with branch pipes P' P2, the

former connecting with a space f above the plate N and the latter with the space d beneath said plate; Q, a damper for closing the upper end of the space c, the same being operated by a rod Q; R, a damper for the upper end of the flue b, the ,same being operated by a rod R; S, adamper, which may be moved to put the magazine F into communication with the space f; S', a damper for the branch pipe P; T, a fire-door; T', a fuel-passage thereat, and T2 a removable chute for the inner tire-pot.

As shown, the plate or flange a is provided with flue-openings g g g2, and the dampers Q and R are provided with`passages h h', respectively, which may be turned to register with the corresponding passages of the ange a.

In the modification shown in Fig. 4 the chambers B and I are connected; but the chamber D is not connected with the chamber I. Instead'it is provided with outgoing pipes la, which may pass directly to a hot- Water-supply circuit, while the pipes J may connect with the heating-circuit. Separate return-pi pes would be provided in such case.

In operation when the heater is to be used as a return-line heater or base-burner the dampers S S are closed and the inner tire-pot Gr and chute T2 removed. The magazine F can then be charged with fuel, and the course of the products of combustion will be as indicated by the arrows in Fig. 1. Should too much heat be contributed to the chamber D, as when the heating and hot-water supply circuits are independent, the draft adjacent to said chamber may be regulated by the dampers Q and R. It will readily be seen that with the dampers S and S closed any gases passing up through the tlues b b on the side IOO of the heater adjacent to the smoke-stack will be caused by the plate K to pass down along the vertical partitions K and finally to ascend to the branch pipe p2. When it is desired to reduce the capacity of the heater and to prevent so far as possible radiation into the room where the heater is located, as in the summertime, the fire-pot G is put in place and the dampers S S are opened to give a direct draft through the magazine F and the due-space c to the pipe P. The eifect in such case would be to heat the chamber D, while the outer walls of the heater as a whole would remain cold. This would be the case particularly where the circuit of the chamber D is independent of the circuit of the chamber B, as in Fig. 4. Of course the chamber D could be arranged to supply either the heating-circuit or the hot-water-supply circuit, or both, and this without causing the circulation to pass through the chamber D.

Many heaters are now in operation which are provided with the base A and the waterchamber B, but no provision is made therein for attaining the economical results attributable to our invention. Such heaters can be converted in to an improved heater of greatly-increased capacity by means of our invention. The interior parts are supported, as stated, by the flange a, which merely rests upon the top of the chamber B. The drum C and other outer parts can be connected readily.

Changes in details of construction within the spirit of our invention may be made. Hence no limitation is to be understood from the foregoing detailed description, except as shall appear from the appended claims.

What we claim as new, and desire to secure by Letters Patent, is-

1. In a heater, the combination of a base, an annular water-chambersupported thereon, a drum inclosing said chamber and extending some distance above the same, a central magazine provided with an upward extension havinga damper thereat, an annular water-chamber separated from said magazine and said iirst-named water-chamber by ann ular spaces, a smoke-stack having a branch connection with the top of the heater and another branch connection at a lower plane, and a damper for the upper branch connection, substantially as described.

2. In a heater, having an annular waterchamber, an annular liue adjacent thereto and a separate Hue, a damper controlling the products of combustion through said firstnamed flue, whereby the degree of heat contributed to said water-chamber may be regulated, substantially as described.

3. In a heater, having an annular waterchamber and an annular flue adjacent thereto, an annular damper near the upper end of said flue and rotatable about a vertical axis, whereby the passage of the products of combustion from said flue may be controlled and the heat contributed to said water-chamber regulated, substantially as described.
